To all whom it may concern:

Beit known that ALFRED A'. HAWLEY, of Methuen, in the countv of Essex and State of Massachusetts, haveinvented a new and useful Machine for Oleanin g Gard-Cylinders', and I do hereby declare the same to be fully described in the following specification and represented in the accompanying; drawings, o which-n Figure lis a top view, and Fig. 2 aside eleyation, of it.

While the said cleansing brush B is in rapid revolution its teeth will en gage with those of the cylinder O and put itin revolution. By means ot' friction applied to either or both ofthe journals ofthe cylinder O, through the friction brake or brakes thereof, the velocity of the curved surface of the cylinder O may be more or less retarded relatively to that of the brush. Thus the rotary brush, while revolving the cylinder to be cleansed, will reinto the box. One end of the spring is fast- ALFRED A.
